Chapter 6.5, Problem 2PE

Interpretation Introduction

Interpretation:

The molar heat of combustion of methanol has to be calculated.

Concept Introduction:

• Calorimetry can be defined as the measurement of changes in heat.
• Two types of Calorimetry are coffee cup calorimeter and bomb calorimeter.
• The change in heat of the system can be determined with the value of the heat capacity of the calorimeter.
• The heat capacity of the calorimeter can be given as,

${\text{C}}_{\text{cal}}\text{=}\frac{{\text{q}}_{\text{cal}}}{\text{ΔT}}$

• The heat capacity of calorimetry is significant because it gives the heat change of the system. The heat capacity of the calorimeter is given by the equation,

${\text{C}}_{\text{cal}}\text{=}\frac{{\text{q}}_{\text{cal}}}{\text{ΔT}}$

Where ${\text{q}}_{\text{cal}}=$ heat measured by calorimeter

${\text{C}}_{\text{cal}}\text{=}$ Heat capacity of the calorimeter

$\text{ΔT=}$ Change in temperature
